Subject: writing a driver for a PC-Card
Sender: owner-freebsd-mobile@FreeBSD.ORG

Hello!

I have a BreezeNet Wavelan PC Card and the sources for its linux driver and
have to make a "port" of it for the FreeBSD.

My question is: I see that the Linux driver requests the card manager to
map both shared and attribute memory 'by hands' in the card init procedure.
In the freebsd drivers I see that the memory is already mapped when the
card init procedure is called (id_maddr set). The manual for the new
(PAO-991011) pccardd says that this is the common ("mailbox") memory.
Is it true? And how can I map the 'attribute' memory? This question is
quite significant for the card because it doesn't use 'traditional'
'i/o ports' model to perform resetting etc.

Please point me to the FreeBSD PC-Card driver creation documentation if any.
Any your help will be greatly appreciated.

Thank you.

Alexey Morozov
